Subject: [noob] name of a variable, at runtime

This seems harder than the usual thing I've been tripping on (and
finding answers in the pickaxe or online).

I have an object: human. It has parts: human.hand human.foot.

How can I say this:
    fred = human.new
    fred.hand  = fred.foot = fred. leg = 'flesh'
    fred.knee = 'plastic'
    fred.head = 'steel'
    parts = [hand,foot,leg,knee]
    parts.each do |part|
        puts "part #{part} is made of " + fred.{part}.to_s
    end # with each part

Am I close?

Thanks,
--Colin
